Standard serial over Bluetooth link - select COM port

Hello,

As mentioned in https://blog.bachi.net/?p=9700, Bluetooth SPP opens two ports when pairing a device:

  • An incoming port is used when a remote device established a connection to your device, and is exposed as the SerialPort service to the remote device.
  • An outgoing port is used to make a connection to the serial port service on a remote device.

Is there a way to modify this behavior and specify to open just one of the two? E.g. incoming port, telling Windows in advanced that the remote device is establishing the connection. I am specially interested also if it is possible to configure from WinRT/Win32 C++ APIs.

Thanks in advance!

    Hello,

    Welcome to Microsoft Q&A!

    As far as I'm concerned, there is no suitable winapi to configure. Usually there are 2 COM ports (incoming and outgoing) are assigned to a device. Who initiates the connection determines whether incoming or outgoing is used.

    Thank you.
